UNITED STATES WILLIAM A. wELLs, OF ADRIAN, MICHIGAN.

IMPROVEMENT IN ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 118,412, dated August22,1871.

To all whom it may concern:

Be it known that I, WILLIAM A. WELLs, of Adrian, in the county ofLenawee and State of Michigan, have'invented certain new and usefulImprovements in Sewing-Machine Attachments; and I do hereby declare thefollowing to be a full, clear, andexact description thereof, referencebeing had to the accompanying drawing forming a part of the same, and inwhich- Figures 1 and 2 represent a plan and a side view, respectively,of the main plate or device for attaching the several devices shown inthe other figures of the drawing to the table of the sewing-machine.Figs. 3 and 4. are like views of the presserplate; Figs. 5 and 6, thesame views of the hammer; Figs. 7 and 8, similar views of the basterFigs. 9 and 10, also like views of the presser-plate in a modified form.Fig. 11 is a section of the latter device through the-dotted line as mof Fig. 9.

Similar letters of reference in the several figures designate like'parts.

This invention appertains to improvements in sewing-machine attachments;and it consists of a main plate or device for attaching the other partshereinafter referred to to the table of the sewing-machine, it beingconstructed and operating substantially as more fully hereinafterdescribed and claimed.

To enable those skilled in the art to which my invention appertains tomake and use the same, I will proceed to describe its construction andoperation.

In the annexed drawing, A A, Figs. 1 and 2, designate the main plate ordevice for attaching the other parts, to be hereinafter described, tothe table of the sewing-machine, it being supplied itself with anopening, a, through which athumb or set-screw is designed to pass toadjust it to the said table when in use. This plate or device is of thecurvilinear form shown in the former figure, above alluded to, or of anyother desired form, and is supplied with grooves upon its upper surface,formed by so bending or turning the edges of its straight portion thatthey shall project inwardly a short distance and rest in such a manneras to leave spaces between the said projecting surfaces and the plateitself, as shown at a a in Fig. 1, the object of the groove so formedbeing for the purpose of separately receiving that portion of thepresser-plate hammer, baster, 8200., having a notch, as seen in thefigures of the annexed drawing, whereby they may be attached to the saidplate A A, and to which plate they are rigidly held when separatelyapplied thereto by means of a pivoted arm, a upon the free end of whichis constructed a raised plate, (see Fig. 2,) which terminates into atooth, entering one of two notches, a a in said plate, and the notch inone of the parts above alluded to when said arm is thrust into itsnotch. The outer ends of the plates a a of the device A are bent upwardat right angles, forming guides 64. a, as shown in Figs. 1 and 2, theobject of said guides being to keep the work or article being operatedupon in a straight line. B refers to the presser-plate, constructedsubstantially as shown in Figs..3 and 4, and modifled in form, as shownin Figs. 9, 10, and 11, and having its base-plate, with notch I),connected to its upper projecting and bifurcated portion (which performsthe work of gathering, rufflin g, and puifing) by means of an ellipticalspring, as shown in Fig. 4, which allows the said plate to accommodateitself to the work being done, and, at the same time, renders it freeand pliable when in use. G is the hammer, the base-plate of which, withnotch c, is supplied upon its upper side with the hemming device 0,which is of a convoluted conical form, as shown in Figs. 5 and 6. 1)refers to the baster, which consists of an upper and lower plate,connected together by means of aflat curvilinear spring, and supplied attheir ends with semicircular projections, which clamp the work orarticle being operated upon when the two edges of the same are broughttogether preparatory to being sewed together, and thus holds the same,obviating the necessity of tacking them together, as is the courseordinarily pursued for securing the work to permit of its being properlysewed. The baster D is supplied with a notch, 01, in one of its flangedportions, (see Fig..,7,) the object of which, and of each of thosementioned in connection with the presserplate and hammer, being for thepurpose stated in connection with the description of the main orattaching-plate A.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 24th day of March, A. D. 1871, in presence of twois-- subscribing witnesses.
